### async_local_storage_unavailable ``` The node API `AsyncLocalStorage` is not available, but is required to use async server rendering. ``` Some platforms require configuration flags to enable this API. Consult your platform's documentation. ### await_invalid ``` Encountered asynchronous work while rendering synchronously. ``` You (or the framework you're using) called [`render(...)`](svelte-server#render) with a component containing an `await` expression. Either `await` the result of `render` or wrap the `await` (or the component containing it) in a [``](svelte-boundary) with a `pending` snippet. ### dynamic_element_invalid_tag ``` `` is not a valid element name — the element will not be rendered ``` The value passed to the `this` prop of `` must be a valid HTML element, SVG element, MathML element, or custom element name. A value containing invalid characters (such as whitespace or special characters) was provided, which could be a security risk. Ensure only valid tag names are passed. ### html_deprecated ``` The `html` property of server render results has been deprecated. Use `body` instead. ``` ### hydratable_clobbering ``` Attempted to set `hydratable` with key `%key%` twice with different values. %stack% ``` This error occurs when using `hydratable` multiple times with the same key. To avoid this, you can: - Ensure all invocations with the same key result in the same value - Update the keys to make both instances unique ```svelte ``` ### hydratable_serialization_failed ``` Failed to serialize `hydratable` data for key `%key%`. `hydratable` can serialize anything [`uneval` from `devalue`](https://npmjs.com/package/uneval) can, plus Promises. Cause: %stack% ``` ### invalid_csp ``` `csp.nonce` was set while `csp.hash` was `true`. These options cannot be used simultaneously. ``` ### invalid_id_prefix ``` The `idPrefix` option cannot include `--`. ``` ### lifecycle_function_unavailable ``` `%name%(...)` is not available on the server ``` Certain methods such as `mount` cannot be invoked while running in a server context. Avoid calling them eagerly, i.e. not during render. ### server_context_required ``` Could not resolve `render` context. ``` Certain functions such as `hydratable` cannot be invoked outside of a `render(...)` call, such as at the top level of a module.
